xslt2's for-each-group makes it easier (or at least easier to read) but
any xslt 1 grouping construct would work here. Muenchian grouping (ie
using keys) is the usual approach, but making the keys unique in
subtrees rooted at each W is a bit tiresome, so unless you have 100's of
X below each W I'd just write it directly in XPath
something like
<xsl:for-each select="W">
<xsl:for-each select="X[not(@Y=../following-sibling::X/@Y)]">
something
I'd prefer this approach if you know all the X elements will be siblings.
